Cygwin Shell可正常访问目录但CMD提示拒绝访问的权限问题求助

大家好，遇到一个特别奇怪的权限问题，想请各位帮忙分析一下：

我在Cygwin的Shell里能毫无障碍地进入UnarchiveAllPatients目录，还能查看里面的文件和子目录，但切回Windows原生的CMD窗口执行cd UnarchiveAllPatients时，却直接弹出**Access is denied.**的错误，完全搞不懂为什么会出现这种差异。

先给大家展示一下我的完整操作流程：

(Administrator: Command Prompt)

E:\dev\Connect>d:\cygwin64\bin\sh

$ PATH=/bin:$PATH

$ ls -l UnarchiveAllPatients
total 25
drwxr-x---+ 1 jhudson Domain Users   0 Dec  1 13:06 Bin
-rwxr-x---+ 1 jhudson Domain Users 297 Dec  1 12:25 UnarchiveAllPatients.vbproj.user
drwxr-x---+ 1 jhudson Domain Users   0 Dec  1 13:06 obj

$ cd UnarchiveAllPatients
$ ls
Bin  UnarchiveAllPatients.vbproj.user  obj

$ exit

E:\dev\Connect>cd UnarchiveAllPatients
Access is denied.

E:\dev\Connect>

补充一下背景：这个目录是通过rsync命令做夜间备份同步过来的，我怀疑是同步过程中权限设置出了问题。我分别用cacls和icacls查了这个目录的权限配置，结果看起来有点混乱，但我自己看不出具体哪里出了问题，麻烦各位帮忙看看：
